Because heterozygous means that the parents contain both dominant and recessive genes the offspring will be 75% tall and 25% short. If you were to draw the punnett squares you would see that there are 3 possible children one with only dominant tall traits two with both dominant and recessive traits and one with only recessive traits.

∙ 14y agoRr x Rr will yield you 1/4 homozygous dominant phenotype (RR), 1/2 heterozygous dominant phenotype (Rr) and 1/4 homozygous recessive phenotype (rr). As for the wording, the homozygous dominant will show the dominant trait, the heterozygotes will follow suit and the homozygous recessive will exhibit only the recessive trait.

∙ 15y agowell, that would be Tt and Tt.... so... 1:2:1 is the ratio of the genotype. 3:1 is the ratio of the phenotype. do you go to MHS?
Wiki User
∙ 12y ago1:2:1, one would be TT , two would be Tt and one would be tt .

Two plants are crossed resulting in offspring with a 3 to1 ratio for a particular trait This suggests?
That the parents were both heterozygous!
When the two haploid gametes contain two different alleles of a given gene the resulting offspring is called?
A heterozygote. An organism with the same alleles at a locus is called a "homozygot".
Why were heterozygous individuals called carriers for non-sex-linked and x-linked recessive patterns of inheritance?
I don't know and don't care
In humans straight toes S is dominant over curled toes s What would be the result of a cross between a recessive male and a heterozygous female?
The resulting offspring will have 50% chance of having straight toes and being heterozygous, and 50% chance of having curled toes and being recessive.
Two plants are crossed resulting in offspring with 3 to 1 ratio for a particular trait?
that the parents were true-breeding for contrasting traits. NOT TRUE. If so, all the offspring would be identical genotypes. Think of a classic cross that gives you a 3:1 ratio and write it out. It would suggest that the parents were both heterozygous for a single trait.

Why does the expected genotypic ratio often differ from the expected genotypic ratio resulting from a monohybrid cross?

What will be the resulting phenotype of two alleles one being dominant to the other recessive allele?
The phenotypic ration in F1 generation will be 3 : 1. Three individuals showing dominant trait and one individual with recessive trait. However, the genotypic ratio will be 1:2:1.That is one homozygous dominant, two heterozygous dominant and one homozygous recessive individuals.

If a heterozygous red eyed female fruit fly mates with a heterozygous red eyed male fruit fly the ratio of the resulting offspring that will have red eyes is while the remaining r?
If red eyes are dominant, then 75% will have red eyes and 25% will have white eyes. The genetic breakdown is: 25% will be RR (homozygous red eyes), 50% will be Rr (heterozygous red eyes) and 25% will be rr (homozygous white eyes).
What do F1 in genetics?
Genotype is a same gene type that is carried by a parent to offspring. Phenotype is appearance, lets say a parent has big ears and the child inherit the big ears.
What is variation what is a natural selection?
variation is the differences in genotypic traits between individuals in a populationnatural selection is any naturally occurring process resulting in differential success of reproduction of individuals depending on the genotypic traits they have expressed as phenotypic traits, the usual means by which this happens is the death of specific individuals prior to being able to reproduce but other events can alter the rate of success of reproduction without the individuals dying (e.g. they reproduce OK themselves but fail to bring those offspring to reproductive age successfully).
What would mating between a true breeding purple flowered pea plant and a true breeding white flowered pea plant produce?
Make a Punnet Square:White HETEROZYGOUS---WwRed HOMOZYGOUS--ww (this one is recessive because the white characteristic dominated in the heterozygous type)So:W ww Ww www Ww wwThese four are the potential types of the offspring, they will either be HETEROZYGOUS WHITE or HOMOZYGOUS RED, no homozygous white
Can a white tiger and a normal bangel tiger mate if so what color is there cub?
Heterozygous - White gene carrier Homozygous - No white gene White tigers are not albinos and do not constitute a separate subspecies of their own and can breed with orange ones, although all of the resulting offspring will be heterozygous for the recessive white gene, and their fur will be orange. The only exception would be if the orange parent was itself already a heterozygous tiger, which would give each cub a 50% chance of being either double-recessive white or heterozygous orange. If two heterozygous tigers, or heterozygotes, breed on average 25% of their offspring will be white, 50% will be heterozygous orange (white gene carriers) and 25% will be homozygous orange, with no white genes. In the 1970s a pair of heterozygous orange tigers named Sashi and Ravi produced 13 cubs in Alipore Zoo, of which 3 were white. If two white tigers breed, 100% of their cubs will be homozygous white tigers. A tiger which is homozygous for the white gene may also be heterozygous or homozygous for many different genes. The question of whether a tiger is heterozygous (a heterozygote) or homozygous (a homozygote) depends on the context of which gene is being discussed. Inbreeding promotes homozygosity and has been used as a strategy to produce white tigers. (From Wikipedia)
